But that doesn't mean that test configs that already set their own timeoutFactor should adjust by the same factor! That just doesn't work for any test with an implicit default timeout.

Yes, this PR change the default timeoutFactor when the tested JVM options do not contains '-Xcomp', and at the same time also multiplies 4 of the timeout value defined in some tests.

So after this PR, the tests which the timeout value has been multiplied 4 will have more timeout value, when the tested [JVM options contains '-Xcomp'](https://github.com/lkorinth/jdk/blob/286a2cc6e989a1c7dcd641bce792c6411bc1d0ea/make/RunTests.gmk#L593).

I do agree this change, what I mean is this change has some side effect.
